show 'USE' label instead of 'CREATE' at init modal if path exists

[lukaszb]

It was strange for me to open the app on another machine, select existing directory I want to use and seeing "Create" label. I was afraid it would override my storage created on another machine (lying within "cloud drive").

Have two questions, though:

1. I'd also update same thing at the storages tab but am not sure if you prefer two smaller PRs or one with both changes
2. Do we have any common place for utils like pathExists functions? I've left it at InitModal component but would prefer to extract it somewhere (as this function would be used for similar check at storages tab)

I answer your two questions.

1. I prefer two smaller PR, because it is easy to review for me. However, if you prefer one with both changes PR, it does not matter.
2. Common place for utils is ./browser/lib

please fix from CI.

@sosukesuzuki all right, thanks. I'll fix lint errors and put pathExists function under ./browser/lib and ping you back. Will create another PR after this one is merged.

Reopening to notify CI to re-run tests - it seems there is some randomly failing test.
