Fixed applying proper theme in FormUriActivity

[grzesiek2010]

Closes #6043

Why is this the best possible solution? Were any other approaches considered?

The whole activity (FormUriActivity) didn't work well with different themes (the problem was not only with that particular dialog described in the issue). I've fixed the issue by applying the same approach (our LocalizedActivity) as we do in other places of the app.

How does this change affect users? Describe intentional changes to behavior and behavior that could have accidentally been affected by code changes. In other words, what are the regression risks?

It's a safe fix so you can focus on the scenario that is described in the issue. I can't see any risk that you would need to be aware of.

Do we need any specific form for testing your changes? If so, please attach one.

No.

Does this change require updates to documentation? If so, please file an issue here and include the link below.

No.
