caja-file: fix future informal date bug

[basicmaster]

If informal date format is used, for future dates the today time format has been used by mistake, instead of the general time format.

Testing today (2023-04-15) with a file having a modification date of 2023-04-21:

I cannot reproduce this problem，How should I reproduce it

[basicmaster]

You need to set the date format to "informal date" (see https://github.com/mate-desktop/caja/pull/1710#issuecomment-1517288663).

Do I use this merge for testing ? Is this PR for repairing 1710

[basicmaster]

This fix affects a similar part of the code as #1710 does: the informal date format. However this is an independent bugfix and not a fix or improvement for #1710; it works separately from #1710.

Confirmed, a file created with touch -t 05151130 test_1 is shown as from today in caja. (heute=today)

With the fix same file is shown with the correct date in caja.
