Ben Peart e692851763 split-index: disable the fsmonitor extension when running the split index test 
The split index test t1700-split-index.sh has hard coded SHA values for
the index.  Currently it supports index V4 and V3 but assumes there are
no index extensions loaded.

When manually forcing the fsmonitor extension to be turned on when
running the test suite, the SHA values no longer match which causes the
test to fail.

The potential matrix of index extensions and index versions can is quite
large so instead temporarily disable the extension before attempting to
run the test until the underlying problem of hard coded SHA values is fixed.
