Allow git-svnimport to take "" as the trunk directory.

Some repositories started with the trunk in "/" and then moved it to the
standard "trunk/" location.

On these repositories, the correct thing would be to call git-svnimport -T "",
but because of the way the options are handled, it uses the default "trunk"
instead of the given empty string. This patch fixes that behaviour.
