[Bug Fix] Restrict AST checker on Boolean Variable (ShishirPatil#256)

This PR removes any AST checker answers that contain the string literals
"True" and "False", thereby restricting the conditionals of the AST
checker to strictly boolean value.

Example:

`[true, "true"] -> [true]`

This PR will stack on top of ShishirPatil#252

Will this change the results of leaderboard? YES

ShishirPatil#253 will updated the
leaderboard with this fix.
