BUG: `MemoryFS.move` fails to change filename.

[tfeldmann]

I've got some strange behavior that I cannot explain.

I'm creating a file Old-name.txt on a MemoryFS, then moving it to a new location under a new name.
Problem is it still has the old name.

Testcase:

import fs
from fs.move import move_file


with fs.open_fs("mem://") as mem:
    old = mem.makedir("Old")
    new = mem.makedir("New")

    old.writetext("Old-name.txt", "Some content")

    print("Before:")
    mem.tree()

    move_file(
        src_fs=mem,
        src_path="Old/Old-name.txt",
        dst_fs=mem,
        dst_path="New/New-name.txt",
    )

    print("After: (Still the old name)")
    mem.tree()

Output:

Before:
├── New
└── Old
    └── Old-name.txt
After: (Still the old name)
├── New
│   └── Old-name.txt
└── Old

Ok it's even more basic than that:

import fs

with fs.open_fs("mem://") as mem:
    mem.writetext("Old-name.txt", "Some content")
    mem.move("Old-name.txt", "New-name.txt")
    mem.tree()

Output:

└── Old-name.txt

This is a known issue I fixed in #510 but I failed to do a new release for that sorry!

Ah I see! Thank you for the fast response 👍

This has hopefully been fixed in v2.4.15 👍

Thanks a lot!
