Save "Path to store imported files" setting on Import page

[AndrewBelt]

Is your feature request related to a problem? Please describe.
On the Import page, clicking "import options" shows the desired import path that can be changed by the user. Unfortunately any changes to this setting will not be used the next time you go to the Import page.

Describe the solution you'd like
When focus of the text field is lost, it should save to the extension's storage so that the next time the Import page is opened, the updated folder path is used instead of the default /ipfs-companion-imports/%Y-%M-%D_%h%m%s/.

Describe alternatives you've considered

Additional context
A changed import path does not save to settings:
