Remove extra space in open dialog.

That space is only used in maximized mode of Files.app. When the extension acts as an open dialog, then there is no need for this space. Along the way, increased the space in Files.app mode to look better.

TEST=Open a browser, press ctrl-o. Verify that there is no extra space like on the screenshot in the bug's description.
