* implement a fix for tags being found in code blocks
still needs polish, consider this a rough draft
* refactor to reuse a local function
uses CheckWrappedInCode to check that there are no code blocks that surround the tag being parsed
* Add more test coverage of MessageHelper.ParseTags
* reset indexes for @ here mention
* add a test case to catch error fixed from prev commit
* wip commit of most test cases working
* fix the Enclosed in block util method
* code cleanup
* lint whitespace
* lint brackets for single line if blocks
* move messagehelpertests to the new unit test dir
* expose internals to the unit test project
this seems to have been breaking the build, since CI would build the merged branch, where rest wasn't exposed to the unit tests
