Daniel Bevenius 8fb4ea9f75 test: add deprecation code to expectWarning
This commit adds a deprecation code to expectWarning and updates the
function to check the passed code against the code property on the
warning object.

Not all warnings have a deprecation code so for those that don't an
explicit code of common.noWarnCode is required. Passing this skips the
assertion of the code.
