Fixed Trade search: ladder filter breaks item properties

Device: PC
Browser: Firefox
OS: Win10

Steps to reproduce:
- Go to 'search trades'
- Start typing out

Gheed
- Select

Gheed's Fortune from dropdown
- Select ladder
- Click full search

-> No matches will be found

- Now go to item type and de-select grand charm
- Hit apply filters

-> Results for

Gheed's are now shown

Anything else to add:
The same applies to other items (

Hellfire Torch,

Annihilus, ..). It appears to be a ladder filter specific problem. I haven't gotten around to doing more in-depth testing but from initial observations it seems as though creating a trade with the ladder filter active removes the item type property from that trade when saving. As a result, it no longer shows in searches that still have the item type defaulted via selecting the item from the dropdown. So far, I have only seen this with charms.

Should be fixed now Schnork, want to give it a test?

Will have only affected

Annihilus,

Hellfire Torch, and

Gheed's Fortune, correct.
