filter-branch: remove an unnecessary use of 'git read-tree'

The intent of this particular call to 'git read-tree' was to fill an
index. But in fact, it only allocated an empty index. Later in the
program, the index is filled anyway by calling read-tree with specific
commits, and considering that elsewhere the index is even removed (i.e.,
it is not relied upon that the index file exists), this first call of
read-tree is completely redundant.
