JEA username and domain

During environment setup in the "Icinga for Windows Management Console" I was selecting the option "Install JEA Profile with managed user "icinga"". This basically runs fine for all checks, but during the checks of MSSQL I found the following issue.
When running the MSSQL checks with IntegratedSecurity on, the login attempt fails. During my investigations I saw Icinga using the server's name as username and the domain as domain (so, login attempt is done with "[domain][server name]$", but it should be [server name]\icinga; this local user has all needed permissions in the database).

Expected Behavior

The check should be green.

Current Behavior

The check fails due to DB connection error.

Steps to Reproduce (for bugs)

1. Start JEA test environment
2. Execute an MSSQL check (in my case, it's either invoke-IcingaCheckMSSQLHealth -IntegratedSecurity true -warning 1s -critical 2s (which returns DB connection error and is red) or Invoke-IcingaCheckMSSQLBackupStatus -IntegratedSecurity (which returns an Icinga error with the above mentioned user credentials and is violet)
3. Besides that, typing $env:username shows the server name together with the $ sign and $env:userdomain shows the domain name. So it's at least not an issue of the MSSQL plugins.
