1421 update logs for Unicode Nul character

[Cmdv]

Description

this fixes #1421

The logs were false in that not the whole row was drop, but instead if parsing failed with a Unicode Nul character the specific column it was intended for is recorded as nul.

This also effected a couple of other places so those were updated too.

[db-sync-node:Warning:75] [2024-01-31 11:02:29.12 UTC]  prepareTxMetadata: Column 'json' in table 'metadata' was recorded as null, due to a Unicode NUL character found when trying to parse the json.

This also fixes #1623 as outputting the full json made logs quite perplexing.

Column 'json' in table 'metadata' was recorded as null, due to a Unicode NUL character found when trying to parse the json.

This is definitely more clear, but I wonder if it's a little too verbose

how about

The 'json' column in 'metadata' became null due to a Unicode NUL character in the JSON parsing process.

That definitely looks better 👍
