Revert "Remove redundant Umbraco exceptions to VS rules"

This reverts commit 5b168d43009dbfa9e5b02dd6be7ee5961059ea61.

Amends #1131 - fixes Umbraco template to compensate for the change in the
VisualStudio template which would lead to issues if the two were used together.
These rules were originally added by @bbodenmiller in #1013
