Respect minimum waiting times when testing in block section mode

[stai1]

In vanilla and as of v0.4.10, coasters in block section mode do not wait for the minimum waiting time when they are testing or ghost train testing. This can make it difficult to get the timing right without opening the ride if the first block section is not the longest one. Because the purpose of testing is to see that a ride functions correctly before opening, minimum waiting times should be implemented as a feature in continuous circuit block sectioned mode and powered launch block sectioned mode
