Invisible pull-to-refresh when slowly refreshing.

[smaky]

After add ins_addPullToRefreshWithHeight.... to tableview there is problem, when slowly pull down tableview. Content inset is reverted to value before pull and pull-to-refresh is invisible.
There is no issue when pull to refresh i pulled down really fast.
Founded solution is in method - (void)setState:(INSPullToRefreshBackgroundViewState)newState
remove [self setScrollViewContentInsetForLoadingAnimated:YES]; to prevent reset default inset for tableview.

Hi, i will need to test it, because it potentially cause several other issue.
