Twenty Fifteen : Hover effect is different in frontend and editor side for the link

[pitamdey]

In Twenty Fifteen, I have added a link to paragraph tag and then I can see the hover effect is different in the editor and front.

In the editor, the text colour change on hover and In the front the text decoration change as well as the colour but both sides colour are also not the same

I have attached a recording for the reference

I think this is ready.

Links rarely are focusable in the editor, so I do not think it is worth setting the outline color too. Changing the text color and removing the bottom border should be enough for those cases (such as clicking on a disabled link within the Latest Posts block).

Twenty Fifteen: Fixes hover effect being different in editors for link.

The link hover effect was different between the editor and front. As links are rarely focusable in the editor this patch does not set the outline color also.
