Importing Characters/Monsters with conditional senses causes exception

[feltz916]

Whenever importing a monster that has a known sense, but it has conditions contained within parenthesis, it will cause vtta-dndbeyond to fail to import.

Example: https://www.dndbeyond.com/monsters/intellect-devourer

Senses: Senses Blindsight 60 ft. (blind beyond this radius), Passive Perception 12

Causes exception: Cannot read property '0' of null source "foundry"

List of known monsters that cause this: /monsters/intellect-devourer /monsters/needle-blight /monsters/psychic-gray-ooze /monsters/vine-blight /monsters/neogi-master /monsters/yuan-ti-nightmare-speaker
