[PATCH 2/4] msi: Resolve source when executing InstallFiles.

This test already succeeds on Wine, but won't once InstallFiles is deferred.

This fixes the failure originally reported in automation.c here:
https://www.winehq.org/pipermail/wine-devel/2017-October/119159.html
In truth that test is broken and should call ResolveSource, but this way
we at least help prevent the possibility of regressions.
