wx: Fix callback problems
Commands could be executed twice, if the command was dispatched
from a callback and caused a recursive invocation of command loop.
Solution is to mark op as -1 before calling wxWidgets.
Also commands could be missed when idle processing was done inside
while executing a recursive callback, solved be always resetting peak
index after idle processing is done.
