Cached auxiliary: RuleEnvironment cannot be resolved to a type

[SimonCockx]

Reproducer:

system com.regnosys.rosetta.typing.Test

auxiliary {
	test(Boolean param) cached
}

auxiliary test(Boolean param) {
	param
}

The generated code contains the following method:

protected Boolean testInternal(final RuleApplicationTrace _trace_, final Boolean param) {
    return getFromCache("testInternal", (RuleEnvironment)null, _trace_, ...);

... but the class RuleEnvironment isn't imported.

This issue goes away if RuleEnvironment is imported for something else, e.g., for a judgement.

Thanks for the detailed report.
I'll try to have a look at it ASAP.
Of course, if you want to try to provide a PR (possibly with a test reproducing the problem)
