testing: add a 'continuous' profile

This gives a good way of letting Hypothesis run until it
finds an error, save that error, and be restarted without it
picking up on the old bug. This lets you run long-running
Hypothesis processes and then perform a manual deduplication
task on the bugs found at the end.

It's not an entirely satisfying way of using this, but anything
much better would require extensive changes to Hypothesis itself.
