[cwarden]

Describe the bug
nap segfaults when moving two snippets from filtered list

To Reproduce
Steps to reproduce the behavior:

1. Create some snippets

$ export NAP_HOME=$(mktemp -d)
$ jot 100 0 | parallel -P1 'echo note {} | nap {}.txt'

2. Start nap TUI
3. Filter snippets. Type /0<Enter>
4. Move first snippet. Type Rx<Enter>
5. Return to misc folder. Type <Shift>+<Tab>k<Enter>
6. Move first snippet. Type Rx<Enter>

Panic:

panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x18 pc=0x542df5]

Expected behavior
After moving the snippet from the misc folder to the miscx folder in step 4, it should only appear once in the list of filtered snippets.

Screenshots
This snippet should no longer exist.

This is happening even when the number of filtered items is the same as unfiltered.
