Workaround for #15

[Moohan]

Fixes #15

When we detect Sex = "All" in the filters it now defaults to using SQL, this PR is dependent on #54

The base branch was changed.

The fix works great!
I noticed testing it on "83b38aa6-73c0-4489-b344-11081e7aa0ed" it does introduce slightly different behaviour when the filtering results in 0 matching rows - rather than returning a tibble with 0 rows it throws the error "Can't subset columns that don't exist.". Possibly just something to note in the docs or do you think worth including a warning / improving the error message?

This should be fixed now - If the query returns no results it will just return an empty tibble.
