Make is_likely_id_string More Strict

[jpdakran]

Issue: 489

Problem:

• The is_likely_id_string regex can eliminate true positives by mistake.
• Ex. Anything ending in id like the name david followed by a non-letter/non-numeric character will match

Solution:

• Make the regex more strict to identify id strings.
• This can be achieved by enforcing the string starts with the id identifier however we lose out on the other typical id_string identifiers like myid, userid etc.
• We can enforce these additional identifiers
• Also enforce the _id identifier and this can exist in the middle of a string
