decompose_uri_query_into_hash has problem with empty strings

Hi,

I have a problem with the named function, when I call ahn via

agi://url/?x=1&y=&z=2

I get

#

/usr/local/src/ahn/lib/adhearsion/voip/asterisk/commands.rb:20:in `inject'

/usr/local/src/ahn/lib/adhearsion/voip/call.rb:218:in `each'

I would have expected nil or "" for y.

A quick&dirty bugfix I did was

--- lib/adhearsion/voip/call.rb (revision 622)

+++ lib/adhearsion/voip/call.rb (working copy)
