Fixes:

• [BUG]: Stop timer method is called unnecessarily  #1262

Proposed Changes

• In the useTimer (frontend) the isActiveTimer was not checking correctly the function isTimerPause it was missing the parenthesis then it was always returning true causing the execution of timerStop() function. This was the main fix in this PR.
• In the backend when stopping the timer it was not checking if the timer was found (if it exists) and if it was already stopped, now it is checking, and logging it as a warn when the timer was not found or was found and was already stopped, it won't throw an error, it will just log it as a warn.

Other changes:

• The default was removed from some types, interfaces and enum
• The constants and helper functions were moved out from useTimer
• It is now treating when a user is trying to change the status of the timer for the status it already was in those cases it will log a warn (it won't throw an error or log as error since it shouldn't break the API)

This pull request closes #1262
