Set-DbaAgentJob - Added parameter test

[andreasjordan]

Type of Change

• Bug fix (non-breaking change, fixes [Bug] Set-DbaAgentJob - error setting OperatorEmail w/o EmailLevel #6847 )
• New feature (non-breaking change, adds functionality, fixes # )
• Breaking change (effects multiple commands or functionality, fixes # )
• Ran manual Pester test and has passed (`.\tests\manual.pester.ps1)
• Adding code coverage to existing functionality
• Pester test is included
• If new file reference added for test, has is been added to github.com/sqlcollaborative/appveyor-lab ?
• Nunit test is included
• Documentation
• Build system

For all three possible types (e-mail, net send, page) now both operator and level have to be set, otherwise a warning is thrown and the command returns.

Also corrected some comments.

Unsure what's going on, but the changes seem to impact other AgentJob commands which causes failures :/

Ok, I'll have a closer look.

[andreasjordan]

Ok, fixed it. Failed test seem unrelated.

rekicked. BTW, for all, if you don't wanna wait for the whole suite of tests to run, include a (do whatever) in the commit message.
appveyor will target any tests matching *whatever* and all the upper-level dependencies (meaning, all tests related to functions USING whatever). In this case, (do Set-DbaAgentJob) would be a good choice, but if you want to save keyboard presses, even (do Agent) works.
