Update credit-card-number-validator.js

[justin-at-bounteous]

Changes:

• Remove: erroneous leading alternation, preventing space characters from being replaced
• Add: replace each contiguous string of space characters, for good measure

Issues Addressed:

• with the leading alternation present, whitespace is not removed and the credit card number always fails validation
