SqlLogin: Verbose messages is missing values

Details of the scenario you tried and the problem that is occurring:

When creating a new login, the verbose messages are missing values for the properties PasswordExpirationEnabled and PasswordPolicyEnforced, should say 'is $false, but should be $true', but the resource does not handle $null values apparently, or wrong variable is used to build the string.

VERBOSE: [APPVYR-WIN]:                            [[SqlServerLogin]Integration_Test] 2018-01-06_04-24-15: The login 'DscUser4' on the instance 'APPVYR-WIN\DSCSQL2016' is Absent rather than Present
VERBOSE: [APPVYR-WIN]:                            [[SqlServerLogin]Integration_Test] 2018-01-06_04-24-15: The login 'DscUser4' on the instance 'APPVYR-WIN\DSCSQL2016' is a  rather than SqlLogin
VERBOSE: [APPVYR-WIN]:                            [[SqlServerLogin]Integration_Test] 2018-01-06_04-24-15: The login 'DscUser4' on the instance 'APPVYR-WIN\DSCSQL2016' has PasswordExpirationEnabled set to  rather than True

The DSC configuration that is using the resource (as detailed as possible):
Any SqlServerLogin configuration creating a new login.

Version of the Operating System, SQL Server and PowerShell the DSC Target Node is running:
n/a

What module (SqlServer or SQLPS) and which version of the module the DSC Target Node is running:
n/a

Version of the DSC module you're using, or 'dev' if you're using current dev branch:
Dev

Start with the SqlServerLogin resource and reproduce the verbose output using a configuration that creates a new login. Check how PasswordExpirationEnabled and PasswordPolicyEnforced values are assembled in the messages; done means the verbose output shows the actual values, including false versus true, instead of blanks.
