bkpr-listaccountevents filter by id

[michael1011]

Closes #7518

It's much nicer to ask the database to filter than getting everything and filtering the output.

time ./cli/lightning-cli --regtest -k bkpr-listaccountevents | grep x 
         "payment_id": "x",

real	0m6,908s
user	0m1,745s
sys	0m0,534s

time ./cli/lightning-cli --regtest -k bkpr-listaccountevents payment_id=x 
{
   "events": [
      {
         "payment_id": "x",
         <omitted data>
      }
   ]
}

real	0m0,074s
user	0m0,002s
sys	0m0,000s

two tiny nits that would be nice to fixup but largely optional imo. i think the CI error is a global/master one?

Addressed the comments.

i think the CI error is a global/master one?

It seems to me like CI is a little flaky. Let's see if the new commit passes that step

Edit: yes, automagically fixed itself
