Before this commit, the behavior disabling the unused snippet assets
performed two checks:
1. It was looking for occurrences for its use in the snippet template
2. It was looking for occurrences for its use in the HTML fields
3. Checked on the occurrences of step 1 and 2 and return result.
In many cases there are already coincidences in the first step, making
the second step unnecessary since this second one is the slowest.
Matches are now checked between steps 1 and 2 to skip the second if
matches are already found.
