Increase timeout of WaitCondition due to ConcurrentTransactions

Currently we have retry logic with random period of delay.
There is a chance, when we have several re-try attemts with maximum
timeout, so it can be a root cause of floating fails, when we have not
enough time for getting all signals.

Also decrease number of signals from 30 to 25, due to small risk, when
one of signals goes to ConcurrentTransaction error.

Note, that all these changes are made in corresponding functional test
and don't affect main code.
