chore: log read / write errors when persisting the telemetry state file

[yulunz]

This adds logging to the read & write operations to the telemetry state file. In particular,

• for read, no error is logged if the state file doesn't exist, which is expected to happen when the user is new. An error is logged otherwise (e.g. file format error, errors when reading an existing file like permission issue).
• for write, any error in the path will be logged.

This commit also puts the instantiation of the Persistence object out of the ClearcutLogger object to avoid circular dependency.
