File attachments file-drop component without allowLinks is off center

[Blackbaud-JeffDye]

Expected behavior

'Drag a file here' button is either centered, or resized to fill a similar width to the file-items below.

Actual behavior

'Drag a file here' button remains the same size, leaving empty space to the right.

Steps to reproduce

Using a file attachments component without allowLinks, with or without an uploaded file, button position/size is off center.

Wasn't sure if this was following a different pattern than what I'd expected, but the only way I've found to override this would be to use a /deep/ style on the class sky-file-drop-col.

Yeah, the sky-file-drop class should probably change it's flex-basis from 50% to 100% when no link area is available.
