[#322] Restore Wallet "greedy" autocompletion

- Changed order of conditions of automatic autocompletion.
- Added a test for validation of autocompletion functionality
- Changed type of test tag on ChipLayout component, as it seems its not necessary to have this one for proper component functionality. The one from the test package is needed here for the newly added test. And other screen components also use only those from the test package.
