do not dismiss views when application is resumed (#605)

* do not dismiss views when application is resumed

* prevents the PasswordNavigationViewController and PasswordDetailTableViewController from being dismissed when the app is put to the background and then brought back to the foreground
* Instead, the PasswordEntities are re-fetched from the context by their path to handle the re-creation of the entities during an update process that could have run in the background

* update SwiftLint to version 0.50.*

* update SwiftFormat to 0.51.*
