logstorage: Modify rearranging file

This commit updates dlt_logstorage_rearrange_file_name() to perform
following:

- If the maximum index isn't equal to maxcounter, do not rearrange the
  file name
- If the maximum index reaches to maxcounter:
  - If minimum index is not 1, do not rearrange the file name
  - If minimum index is 1, check if there's any indexes which the gap
    is more than 1. If exists, take those indexes as latest and oldest.
