Summary:                    [patch] Blank FORWARD_CONTEXT is not ignored
Description: 
Once you have set FORWARD_CONTEXT=some-context in your dialplan, it is not
possible to "unset" the channel variable. Therefore the only way to unset
it is to set it blank:

exten => exten,n,Set(FORWARD_CONTEXT=)

However this appears to result in Asterisk using a non-existent blank
context for the forwarded call resulting in it failing.

Since there is no way to reset a context, I would expect this to treat a
blank context as if the variable was not set.
