Fixes the delete button text

[RustyPotato]

This will fix the text shown on the delete button when deleting a photo.

This doesn't have an existing issue item. Would you like me to create one?

This fixes the issue by properly referencing dialogs (variable) instead of dialog (undefined).

• Add a test that triggered the bug before fixing it.
  I wasn't able to find any tests that would address .vue files (like the one edited here). If you could point me in the right direction though, I'd be happy to add one.
