Fix simple switch to not progress a call when call already progressed.

If a simple switch was started on a device and then a specific call
made (such as redial or speed dial), on timeout of the simple switch
the call would be attempted again. This patch only allows the simple
switch to make a call if the substate is still in the collecting
digits mode.

Also added small debug message to dialAndAactivate sub. 

Tested by snuff and myself.
