cli: replace last use of evaluate_revset() with evaluate_programmatic()

evaluate_programmatic() should be allowed here. AFAIK, the contract is that
the expression should never contain any bare symbols and "fallible" symbol-like
expressions, which doesn't apply to branches() and remote_branches() functions.

evaluate_revset() is removed because there are no callers. However, it's simple
and basic function, so we might want to reintroduce it if needed.
