Revert "Profile shortcuts switch profile instead of opening new tab"

This reverts commit d689ba5403ceb998013fc99de6758976f8509e98.

I should have tested this more; this breaks a number of things as
switching doesn't execute the 'Command'. Since the next release is
close, let's just revert for now.
