fix: Adjust workaround for #973

The previous fix was assuming that _CachedBuildStaticWebAssetItems were ambiently provided to the server project, but it may happen that _CachedBuildStaticWebAssetItems is not always populated.

This change moves from using `_CachedBuildStaticWebAssetItems` before it's generated by `GetCurrentProjectBuildStaticWebAssetItems` to after it's been generated. This is done by changing the targets of the msbuild invocation in `ResolveReferencedProjectsStaticWebAssets` so that it uses our target as the invocation output, instead of the original one.
