Fix rebuild

[KevinRansom]

1. Parameterization of resources caused us to rebuild a few projects.
2. The test that validated rebuild, didn't check all of the necessary files, and so missed the issue.

PR fixes the issue and the test.

Thank! I've confirmed this fixes things.

(On my somewhat slow machine I'm now seeing 37sec idempotent rebuild times for .\build -norestore)

It should be noted that build -build doesn't work, but this command is available according to build -help. (I think the option can just be removed)

@dsyme@KevinRansom if you open VisualFSharp.sln and set VisualFSharpFull as the startup project, ctrl+f5, launch the experimental VS hive, close it, then launch ctrl+f5 again, what happens?

[KevinRansom]

@abelbraaksma , @cartermp . this addresses the specific issue of un-necessary rebuilds and the test that ensures it works. Please create seperate issues for unrelated build idiosyncracies.

Thanks

Kevin

I'm not referring to any specific idiosynchracies. I'm just curious if this affects the inner loop when building VS tooling and using a VS hive to experiment with changes or debug. Rebuilds today weren't really a problem for me, but I also have a fairly fast machine so perhaps I just didn't notice.
