Convert more manual cases of PidginAccountChooser away from GtkComboBox

Convert more manual cases of PidginAccountChooser away from GtkComboBox
These were missed in /r/1991, but needed a bit of refactoring anyway in /r/1997.
Testing Done:
Tried out the Join a Chat dialog, but only compiled for the request stuff.
