[chirp_devel] [run_tests] support for bank models with channels always tied to a bank, fix #3119

The run_test script has no support for bank models in which a channel must always be tied to a bank.

I found this in the development of a new driver in issue 2999, that driver is ready but can't go to the daily build until this is fixed.

This patch fix this, all you have to do is add a variable named channelAlwaysHasBank to your model class and make it True.

Cheers, Pavel.
