Handled invalid timestamp format in filters

fix https://linear.app/tryghost/issue/SLO-85/fix-http-500-on-contentposts

- in the event we give the incorrect format in a filter, MySQL will
  throw an error and we'll throw a HTTP 500 error
- we can capture this error and return a more useful error to the user
- ideally we'd do this in a validation step before attempting the query,
  but parsing this out of NQL and detecting which columns are DATETIME
  could be quite tricky
