Missing locales mask error reports

[symcbean]

sysPass Version
3.1 (311.19121601)

Describe the bug
If setLocale() fails, the logs do not show the real reason for faults.

To Reproduce
This was observed on an Ubuntu 18.04 host which, out of the box, only supports the default POSIX locales:
C
C.UTF-8
POSIX

Expected behavior
If setLocale() fails, system should fall back to a default / it might be nice of the installer checked this

Screenshots
If applicable, add screenshots to help explain your problem.

Event log
error #1 was reported before adding locales, error #2 after....

Hello,

it's an error message and it doesn't modify the app behavior, so messages are displayed using the original language (English).

This is the current code implementation:

To fix this check in your php.ini file the intl.default_locale variable and set it to something like en_US

intl.default_locale = en_US
