Memory leak detected by LeakCanary

[banasiak]

Hi,

When using this library, com.canelmas.let.DelayedTasks.tasks appears to leak an instance of the fragment that uses it. Below is a LeakCanary log. Please let me know if I can provide any additional information to help debug this issue.

Thanks!

@canelmas any update on this?

[canelmas]

@PiotrWpl unfortunately not.

I'll definitely not be able to look into this in the next couple of weeks. Please feel free to contribute or make any suggestion.
