blast: fix 30 hz with desiredPresentTime

When a transaction is applied on the main thread, first the transaction
is applied and then handleTransaction is called. If we realize a
transaction requires a traversal when we are applying it, handleTransaction
will do a traversal. Since handleTransaction will preform the traversal,
there is no need to schedule a wake up for the next frame to preform
an unneeded traversal.
