Wildcarding not working properly against content with asterisks

[tylermurry]

Trying to do a wildcard match against content that contains asterisks leads to a false match. For example:

"Here is some body with asterisks ***"
with a wildcard match like
"Here is {{*}} with asterisks ***"
will fail.

Adding the following test to stringSimilarity.test.js will expose the issue:

  it('should match a target with an asterisks against a wildcarded source', () => {
    expect(stringSimilarity(`before${WILDCARD}after*`, 'beforeabceafter*')).toBe(true);
  });

Looking into this now, hopefully I can solve the issue.
