refactor: isRedirectPageActionsContext

Added ipfsPathValidator.isRedirectPageActionsContext with tests:
Per-site toggle won't be shown on internal pages and non-IPNS urls
loaded from local gateway (confusing to users)

Removed redundant variables in Browser Action context and made UI less
jittery.
