ccmake: Fix rendering on window resize

Repro steps: configure (without errors), the logs are displayed then the
cache is displayed again, resize the window up -> the logs are
redisplayed after resize instead of the cache

The 'CurrentForm' pointer were left pointed to the last log message
form, this resets it to the main form when configure or generate is done
