[core] Fix regex for sanitizing date constructor in js_to_json

Given the following JavaScript code as string:

    [new Date("foobar"), '("baz")']

The greedy quantifier's usage matches the string till the last quote instead of just the text inside the parenthesis. This patch fixes that using the `STRING_RE` regex for matching string literals properly.

Also updated tests.
