Bugfix MF during suspended capturing

Currently, a guiding deviation while the mount is waiting for capture completed leads to the result that after the meridian flip is completed, neither guiding nor capturing is restarted. This is not appropriate, since guiding deviations lead to restarting captures and not to aborts. This should remain true if a meridian flip happens in between.

Test Scenario

• Create a capture sequence with several frames, each capture should be 20secs at least
• Select "Guide Deviation" in the capture module to ensure that a guiding deviation suspends capturing
• Position the mount close but east of the meridian
• Start guiding and start capturing
• As soon as the mount status is "Meridian Flip waiting", send a guiding pulse so that a guiding deviation occurs
• Now capturing should suspend and the meridian flip should occur immediately
• After the flip is completed, guiding should restart and capturing should continue

There is a special test case testSchedulerGuidingDeviationMF in TestEkosMeridianFlipSpecials that tests all permutations.
