Title: Fixed the display bug, when called the insertSections:

In here I think it doesn't need the animation but the transaction, it would cause some issue of display.
I resolve the bug when user insert the new sections, the cell will display with a blink animation at the first operation.
But I don't know why the next operation wouldn't reproduction in the pre version.
