loadGeometry() will not work if an empty table of same name exists

[kzollove]

Line 35 loadGeometry.R checks if table exists. If exists, doesnt load table.

This is almost always ideal, except in the rare case that a table starts to load, fails, and an empty table is left in database.

maybe loadGeometry() needs an overwrite flag?

I think a better and easier solution is to add a simple "if table exists AND table has more than zero rows" logic to loadgeometry.

Even better would be a try-catch on the importGeomTable function... if failed, delete the empty geom_table instance

Check if this is still a bug, then fix immediately
