Fix race condition for WaitCondition with several signals

This fix is based on changes introduced in patch
Ibf9dd58a66a77d9ae9d4b519b0f11567977f416c.

Follow changes were done in this patch:
 - According previous item code for calculating metadata of
   wait_condition_handle was moved to separate method -
   normalise_signal_data().
 - Same method was implemented for BaseWaitConditionHandle class, which
   returns original signal data without changes.
 - handle_signal method for BaseWaitConditionHandle class was updated:
   * all code related with updating and verification metadata was moved
     to merge_signal_metadata internal method, which will be called from
     metadata_set method.
   * if/else block was changed to raise error in case, when metadata has
     wrong format, so else section was deleted.
 - corresponding tests for waitcondition resource, which expect several
   signals was added.
