Mistake with "at least one filter" and a pair of "All these tags"

[7tonin]

Hi,
when filter second radio is checked "Photos must match at least one filter" (OR) and a pair of "All these tags" (AND) is set as follow:

• The first with tag1a AND tag1b, and
• the second with tag2a AND tag2b.

There is a problem to count, and to save. Very long. And the result is not what I expect.
I expect the SQL WHERE to be somehow like (tag1a AND tag1b) OR (tag2a AND tag2b).

Don't need to open an issue if you already have a fix and a PR
