Fix categories searching error when uploading photos

[zihanpan]

Description (required)

Fixes #5872

1. Adjustments to error handling logic:
   Added the isInitialLoad status variable to track whether it was an initial load. This variable is set to true when the page starts loading and false for the first call to searchForCategories to ensure that no error messages are displayed during the initial loading.

2. Null input processing:
   In the searchForCategories method, a check for whether the input is empty has been added. If the input is empty and the initial load is not categories_found, the call view.showError(R.String.no_categories_found) shows an error.

3. EditText handling:
   Ensure that edittext continues to receive input after ErrorShow is triggered, and that categories cannot be retrieved due to conflicts

I just tried this branch.

Unfortunately, at the categories step, the suggestions list was empty.
There should have been at least some suggestions based on history and location.
As soon as I started typing in the search field, all suggestions (based on history and location) appeared immediately.

Would you mind checking?
Thanks! :-)

Here suggestions do not disappear upon erasing the search:

Thanks for bringing this to my attention! I’d be happy to check and investigate the issue further.

I'll take a look at why the suggestions list might not be appearing initially and see if there are any improvements we can make.

I’ll keep updating!

Did you get a chance to check? :-)

Another issue is that sometimes the previously selected category is pre-selected.

And it seems like selecting a depiction (such as cat) does not make the matching category (Cats) to be suggested in the categorization screen.
