The old variant is still working but setting "cafile" is deprecated
since version 3.6 [0] and generates a warning:
DeprecationWarning: cafile, capath and cadefault are deprecated, use a custom context instead.
But without this patch "fetchRepoProject" still fails with
"error no host given" (see 337380ea1d).
