d10n 39c61288e8 Fix git hunk status disappearance on CursorHold 
When using vim-gitgutter and fugitive:

The hunks extension and the branch extension work as expected when the
file is first loaded; both parts are added to the statusline.

Once the cursor is moved and stopped for &updatetime ms:

1. The branch extension clears b:airline_head on CursorHold
2. Somehow (?) airline#statusline gets called on CursorHold
3. The hunks extension returns '' when b:airline_head is empty, causing
the hunks to be removed from the statusline.

It doesn't make sense to clear airline_head just because the cursor
moved, and the commit message adding the line doesn't say why:
13297cee03

Commit 174b7e1962 relies on airline_head
being set.

Debug detail:
