A different approach to ensuring that a (unique) relevent split from the currently-pending transaction is always in the split list before we load it.

+	* src/register/ledger-core/split-register-load.c
+	(gnc_split_register_load): Ensure that a (unique) relevent split
+	from the currently-pending transaction is always in the split list
+	before we load it, preventing transactions from disappearing from
+	a register while being edited, but without saving the entire (and
+	maybe partially-invalid) split list around for a while. Fixes bugs
+	108347, 125480, 141287, 153183, 168630 (and maybe 126471).

+	* src/register/ledger-core/split-register.c (gnc_split_register_destroy_info):
+	* src/register/ledger-core/split-register-p.h (struct sr_info):
+	Remove saved_slist.
+
 	* lib/libqof/qof/qofevent.h (QOF_EVENT_CREATE):
 	Fix event values.
