INTL-1250: Fix for creating two copies of identical messages when they used double quotes

[alanknight-wk]

Motivation

The codemod could create duplicate messages for the same string if the original source code used double quotes. This is because the toSource() method in the analyzer included the quotes for a string literal. We would end up comparing "Search" to 'Search', and failing because the quotes aren't the same. We should consistently handle the strings with quotes removed.

Changes

Add a utility method that gets the string without quotes in a consistent way, and call it. Add tests, and fix one test that seemed to be expecting the incorrect result.
