When upgrading and defaultFederationConfig has the incorrect version

[favvojohan]

When upgrading and defaultFederationConfig has the incorrect version we give a warning but should do more.
Otherwise there will be an error later on (line 385) in Update-ADFSTKInstitutionConfiguration

Line 75
if ($defaultFederationConfig.configuration.ConfigVersion -ne $currentConfigVersion) {
Write-ADFSTkHost confNotAValidVersionWarning -Style Attention
}
