refactor: remove cell::RefCell, rename TIMERS_QUEUE variable, and etc. (check desc)

Removed unused import, renamed static variable (TIMERS_QUEUE ->
TASKS_QUEUE) and refactored get_instance() and show_infobar() methods.
Return value has been changed (Self -> &'static Self) in get_instance()
method.
A check for opening an infobar has been added and renamed used static
variables in show_infobar() method.
