When two goroutines attempt to access the content of the buffer log writer, they must be made thread safe with a write mutex.
The buffer log writer is only used in testing.

- If the caller function has generics then
`runtime.FuncForPC(...).Name()` will not show the generic types and
instead collapse it to `[...]`. Remove this suffix from the function
name.
- This fixes an issue where the logging of functions that use generics
such as `db.Find` to be logged as `]()` instead of `Find()`, as the last
dot in `[...]` was being used as a cutoff point.
- Unit test added.
