Ignore query failure in Matomo for WordPress when checking if logtmptable exists (#17158)

Needed this in https://github.com/matomo-org/wp-matomo/pull/417 and documented it in https://github.com/matomo-org/wp-matomo/wiki/Database

Previously, I had detected this query like this: https://github.com/matomo-org/wp-matomo/pull/417/files#diff-c4e75ddbbcdde3ba408b5a87e273371dd3420a5d0b90a87bb4295e81787cdc31L365 but now it looks like `SELECT /*+MAX_EXECUTION_TIME....` and it's quite hard to detect it without trying to reconstruct the query or using regex. This way it'll be more future proof
