Remove unnecessary wxBeginBusyCursor() from generic dialogs

For some reason lost in the mist of time (this seems to have started in
92afa2b150 (Did somework on the generic dialogs, Renamed wxBox ->
wxBoxSizer Removed old dialog layout code,, 1999-08-11)) we were setting
busy cursor while creating several generic dialogs.

This is completely useless, so just stop doing it.
