Fix for bug#47019: Assertion failed: 0, file .\rt_mbr.c,
line 138 when forcing a spatial index
Problem: "Spatial indexes can be involved in the search
for queries that use a function such as MBRContains()
or MBRWithin() in the WHERE clause".
Using spatial indexes for JOINs with =, <=> etc.
predicates is incorrect.
Fix: disable spatial indexes for such queries.

sql/sql_select.cc:
Fix for bug#47019: Assertion failed: 0, file .\rt_mbr.c,
line 138 when forcing a spatial index
- disable spatial indexes for queries which use
non-spatial conditions (e.g. NATURAL JOINs).
