Since structured error data from clues is not added
to error message logging from assert and require,
we're slicing out data that is valuable to debugging.
This adds a package in tester which wraps the error
assertion funcs so that structured error data is
appended to all failure outputs.
## Description
Use the new suite.Suite wrappers in tester package. Also update suite.Run and some nolint directives.

## Description
Encode all paths given to kopia with base64URL to ensure no special characters that kopia can't handle end up in there. The encoded paths are not stored in backup details nor are they ever surfaced to the user. This also works around the previous limitation where Corso was unable to properly backup or restore exchange email layouts that had folders containing `/` characters
