[3.2][Kernel] Change Class.forName() usage in the `LogStoreProvider…

…`. (delta-io#3304)

Look for the `LogStore` class more broadly in the class loader than just
the thread local's class loader. The thread context class loader
requires the Thread local variables to have the `LogStore` in it, but
this class loader may not have all the dependencies wired up.

Not tested yet.

Fixes delta-io#3299.
