Fixed regression #2284

[GLakovnik]

Fixes #2284

The -B and -V flags now reset each other in hledger-ui. This gives the expected behavior:
State : Normal -> keypress B -> State: B
State : Normal -> keypress V -> State: V
State : B -> keypress V -> State: V
State : B -> keypress B -> State: Normal
State : V -> keypress B -> State: B
State : V -> Keypress B -> State: Normal
