@wing328 @ggershoni
This PR does not have backward compatibility for these 3 patterns in definitions.
But, it seems that those regexp patterns are not correct regular expressions.

I think we do not need to support. WDYT?

I was trying to ensure that if forward slashes where not surrounding the inputted regex then they would be added to force the inputted text to be a treated as a regex literal... I wanted to prevent someone from putting in malicious code via pattern. The Mustache template doesn't surround the regex with quotes anymore.

I was thinking we could put forward slashes in the Mustache template but then we might have an ending forward slash when we didn't want one i.e. /^pattern$/i/.

@meganemura I read the code in addRegularExpressionDelimiter and I like it. Thanks heaps for the refactor!

@wing328 I am happy to have those 3 tests removed. @meganemura is right, they are not correct regular expressions.

@ggershoni Thanks for reviewing 👍
