REPL: Handle message from complete_methods! when max methods is hit

[IanButterworth]

It appears #56963 wasn't a proper fix (although curiously it did appear to work #56963 (comment))

[newptcai]

I got this problem on 1.11.3 when I type

sympy.apart(e┌ Error: Error in the keymap

and hit tab.

This PR fixed it.

[danielwe]

Looks like this might also fix #57127? I'm not able to verify myself at the moment, but it's the same error.

[giordano]

Do we have a regression test for this already?

[IanButterworth]

No, I didn't immediately see a way to. It may not be complicated.

[giordano]

A systematic reproducer for me is for example rand(Fl<TAB>, #57127 used write(x<TAB>
