Scryfall mana cost filter

[soph-harris-31]

Describe the bug
When multiple of the same mana symbol is used in the scryfall mana filter (e.g. "mana:bb"), only one of the symbols is counted (e.g. cards that only have 1 black mana symbol in their cost will still appear).

To Reproduce

1. Go to the list section of a cube.
2. Click on "filter".
3. Type in "mana:bb" (or "mana:rr", etc.)
4. Cards with only one black symbol in their cost will appear.

Expected behavior
Expected only cards with two or more black symbols in their cost to appear.
