Wrong z-index on modal error message in manual setup

[rolodato]

Repro steps:

1. Install the plugin
2. Choose manual setup
3. Focus the token field, leave it empty and hit Enter
4. A modal appears behind the current one, which can't be seen:

Not z-index, it is because hitting enter submits the form which produces it to show again the popup to pick which type of setup you want to use

will check, but if you hit continue it should not affect to the entire flow.

Fixed in #468 and merged into dev ... disabled the enter key in that modal.
