[PATCH v4 03/17] fix: utils: add a substr for the patch media caption

[Muhammad Rizki <kiizuha@gnuweeb.org>]

Commit bb8855bf5e344 ("Fix the storage management after the refactor was
happened") did not care with the caption length when sending an
attachment. This leads to error when the caption length hits the
limit. Add a substr() call to cut the caption if it's too long to
avoid such an error.

P.S.: <sic> at the "was happened" part.
