txhandler: service does not restart after node catching up #4809

The txHandler and txSyncer are stopped when catching up from a catchpoint, and started again afterwards.

But they never really start. The main loop of these services rely on a context to stop. That context is canceled when stopping. Then, when the services are started again, the contexts remain canceled, which leads for the service to immediately end.

The fix is to create a new context when starting these services.

This PR fixes the txHandler part of #4775

The fix is good, please tweak the test a bit. Is it stable enough?
