trim keys before attempting import

When pasting from e.g. signal-desktop, private keys can have a trailing
newline that isn't readily visible. As a result the import mysteriously
fails with a "Private key is not recognized" message.

This is fixed by trimming whitespace from the ends of keys before
attempting to add them.
