Include more statements in code coverage

[fflaten]

PR Summary

Extends code coverage to include break, continue, exit and throw statements. return is not included due to inconsistent behavior (though return 123 is already covered as a command expression)

Adds sort after Group-Object to save future headaches with inconsistent report/output order in Windows PowerShell vs PowerShell 6.1 which sorts by default.

Fix #1465
