AMI Traces with the issue.

Supposing we have a previous bridge between iax2/pbx8-22092 and iax2/pbx8-3748, this is the story:

1º) We launched a bridge between iax2/pbx8-22 and iax2/pbx8-22196
2º) Asterisk unlink iax2/pbx8-22092 and iax2/pbx8-3748
3º) Asterisk link iax2/pbx8-22196 and iax2/pbx8-22092, what is wrong!

PD: I write down within the document all notes beginning with ###
PD: I changes the callerid phones tpo 123456789 for privacy reasons.

> Sometimes happened to me that trying to make bridges, through AMI, some of them are made linking channels wrong that I said.
> For example, in a specific moment, I have next 4 channels to bridge, originate in such order, ch1 before ch2, ch2 before ch3, and so on:
> ch1: dahdi/i1/123456789-c145
> ch2: iax2/pbx8-19952
> ch3: iax2/pbx8-19
> ch4: iax2/pbx8-28577
> First, I tried to link ch1 and ch2:
> action: bridge
> actionid: eee7463b-8897-4b1d-b12d-e82957a4c888
> channel1: dahdi/i1/123456789-c145
> channel2: iax2/pbx8-19952
> And is done ok:
> event: bridgeaction
> privilege: call,all
> timestamp: 1414076642.188133
> response: success
> channel1: dahdi/i1/123456789-c145
> channel2: iax2/pbx8-19952
> Second, I tried to link ch3 and ch4
> action: bridge
> actionid: eee7463b-8897-4b1d-b12d-e82957a4c888
> channel1: iax2/pbx8-19
> channel2: iax2/pbx8-28577
> But in this case, instead of receive an ok with above channels, I've received:
> action: bridge
> actionid: eee7463b-8897-4b1d-b12d-e82957a4c888
> channel1: iax2/pbx8-19952
> channel2: iax2/pbx8-28577
> Notice that the bridge were done between ch4 and ch2, instead of ch4 and ch3.
> We made a workaround of this issue launching the action bridges with their uniqueid's instead of channel name's. But I wanted to open an issue for your knowledge. I don't know if is known or not, I don't find it in the issue tracker.
> PD: We realized of this issue checking in the code, the function ast_channel_by_name_cb in main/channel.c, which matches channel names taking only the first part of the name.
> PD2: I'm really sorry because I don't have any AMI traces of this issue, happened time ago. 
> PD3: Sorry for my English. I hope to be enough clear.
