Description

Add missing PHP script into the replacements loop from PR #13

Motivation and Context

The MISP application has its source under the app/ directory. PR #13 took care of only once replacement, but there was a missing PHP script with "admin@admin.test" set statically on it which did not make it to that PR.

So, after looking for more entries to replace and filtering out only the PHP-related code under app/ we:

• Replace the default admin user also on app/Console/Command/Ls22Shell.php;
• This commit add that script to the loop and shall fix all PHP scripts with hard-coded entry for "admin@admin.test".

• How Has This Been Tested?

Same as mentioned on pull request #13
