Motivation

formatISO, formatToNow and formatToNowStrict only reject an empty input, then hand the result of
parseJSON straight to date-fns:

const p = parseJSON(s);
return format(p, layout || FORMAT_YMD);   // RangeError: Invalid time value

A value that is not a date makes every one of them throw. formatISO is what
transDataForOverview uses for the chart's x-axis, so one malformed time string in a series takes
the metric page down instead of leaving a gap.

Change

Check isValid(p) after parsing and return '' when it fails, matching the existing empty-input
behaviour.

Verification
