select_register incorrectly shows the oldest value in registers

[xJonathanLEI]

Summary

Most commands overwrite the entire register with a Vec of size 1, so at any given point in time there's only 1 value in the register. However, some commands like search maintains history and actually pushes to the register instead. Currently, the select_register command (") incorrectly takes the oldest value for these stacked registers instead of the latest one.

Discovered this bug while working on #5112 :)

Reproduction Steps

Simply make two different searches, then press " to see the list of registers.

In the list, " would show the earlier search pattern instead of the latest one for register /.
