5.3 regression: surveillance:* and camera:mount proposed values disappeared

[chrt223]

• surveillance kind: public, outdoor, ...
• camera:mount: wall, pole, ...
• surveillance:zone: building, entrance, ...

For these 3 tags, a couple of usual values used to be suggested in 5.2. Now, only an empty one:

Even for previously inserted nodes, the values are preserved but the frequent alternatives for surveillance (kind), surveillance:zone and camera:mount are absent and only an "empty" value being proposed (the white circle on the right) :

It used to work in 5.2

There is little visibility about the presets.db bundled at build-time with the APK

• It's precompiled
• without a clear version (at least in the logs or in the filename itself)
• There is no hashing/integrity either
• and comes from a "untrusted" (= unofficial) source (https://textual.ru/presets.db) whose content can change anytime

That being said, roughly diffing the DB didn't show obvious changes specific to surveillance:*. The value for camera:mount in the combos table is identical. Something else should explain it's absence from the UI in v5.3...

Key names with semicolons might be broken by my hacky introduction of xmas:feature main key. All the prefix-removing functions were eager to just leave feature, so I had to rewrite them — and forgot to test on fields. This will be fixed in the next version. Thank you for reporting!
