Fix undo toast rendering

When a long text is provided for the undo toast, the text gets mixed with the button. It was fiine for the close button as 'padding-right: 34px;' was just right for it.

This PR moves to flex layout to make the toast more responsive.

+ Add 'display: flex' to the toast and to the undo button container
+ Remove the 'position: absolute' for the close and undo buttons so they get placed by the flex algo
+ add some margin-right to the undo button because it was to close of the text
+ Change the padding to '0px 12px' as 12px top and bottom is too much when the close and undo button are not placed absolutely
