[TASK] Remove useless text from logging module

The text about the time restriction inside the logging module can be
removed because:

- if no time filter is used, it takes place in the UI by giving the
  information that the search starts 1970
- if the filter is used, the information can be found inside the filter,
  just like for all other filter options
