Fixes around caching

[iamdefinitelyahuman]

What I did

Fixes related to caching:

• do not cache eth_sendTransaction and eth_sendRawTransaction responses - when combined with tx replacement this can leave the main thread stuck on a loop forever, waiting for a lock to release. Maybe related - Stuck transactions - graceful handling? #1115
• gracefully handle any exceptions raised when creating a filter after the initial filter was created successfully. In some cases (looking at you, BSC) public nodes allow a filter to be created and queried several times, then disable and rate limit that specific endpoint. Related - deploy script returns 'Exception in thread Thread-1:'…sometimes #1159

How to verify it

Do stuff, see what breaks.
