FIXED: Queue triggered propagators to be processed after pexp/3 finishes

If reification constraints (such as reified equality) are triggered
here, then they may wish to disable this propagator and remove
attributes from auxiliary variables. If the pexp/3 propagation is
interrupted for that purpose, then the attributes will be
unintentionally reattached by the following fd_put/3 calls in this
propagator. We must ensure that this propagator completely finishes,
so we queue the triggered propagators for later processing.

geq/2 implements propagator activation outside the queue, and thus
should not be used in propagators in the way it was used here.

pexp/3 by itself may not seem particularly important. However, it can
