fix(dav): change type of propertyvalue column to blob

The propertyvalue column can contain null 0x00 characters values because of serializing PHP objects since #30368. This truncates data in text fields, but not blob fields. We start by removing invalid value and altering the column to match the new type.

That's what Sabre PDO's being doing in the first place 🙈

Closes #37754
