#14538 Well path: Preserve renamed file well name without breaking legacy projects

Reverts the unconditional change from commit 74ffc822f2 and replaces it with
a safer fix: only skip re-initializing the well path name from the source
file on reload when a name has already been set. Older projects that never
serialized the well path Name field (e.g. TestCase_RFT_PLT/RegressionTest.rsp)
still get their name populated from the file on load, while renamed well
paths in newer projects keep their custom name across reloads.

Restores the RMS well round-trip test that verifies a renamed well path
name persists after save/reopen.
