<issue_title>Login.EnumDatabaseMappings returns null unexpectedly</issue_title>
<issue_description>Create a login on the server using SQL Authentication
Create a user in a database for that login
call Login.EnumDatabaseMappings.
It should return a collection with 1 entry at least, but sometimes it returns null.

var login = new Login(db.Parent, GenerateUniqueSmoObjectName("login"))
                {
                    LoginType = LoginType.SqlLogin,
                    
                };
                var pwd = Guid.NewGuid().ToString();
                login.Create(pwd);
                var credential = new Credential(db.Parent, GenerateUniqueSmoObjectName("login")) { Identity = "someidentity" };
                var dbUser = db.CreateUser("loginUser", login.Name);
// this assert can fail
                Assert.That(login.EnumDatabaseMappings()?.Select(m => m.DBName), Has.Member(db.Name), "login.EnumDatabaseMappings");

This is the query:

create table #loginmappings( LoginName sysname NULL, DBName sysname NULL, UserName sysname NULL, AliasName sysname NULL )
declare @db_name nvarchar(512)
declare crs cursor local fast_forward
	

 
	for ( select name from sys.databases where 1 = has_dbaccess(name)) 
			


open crs 
fetch crs into @db_name
while @@fetch_status >= 0 
begin 
	set @db_name = quotename(@db_name)
		

 
	exec('use ' + @db_name + ' INSERT #loginmappings select suser_sname(u.sid), db_name(), u.name, null from sys.database_principals AS u where suser_sname(u.sid) is not null')
			

 
	fetch crs into @db_name
end 
close crs
deallocate crs
		


SELECT
logmap.LoginName AS [LoginName],
logmap.DBName AS [DBName],
logmap.UserName AS [UserName]
FROM
sys.server_principals AS log
INNER JOIN #loginmappings AS logmap ON logmap.LoginName=log.name
WHERE
(log.type in ('U', 'G', 'S', 'C', 'K', 'E', 'X') AND log.principal_id not between 101 and 255 AND log.name <> N'##MS_AgentSigningCertificate##')and(log.name='login_Login_apis_work_correctly824ead3d-8f57-4c48-9f19-59c8dd560808')

drop table #loginmappings
