Unknown function when editing certain shell scripts

[nk53]

Does this bug happen when you install plugin without vim-polyglot?
No.

Describe the bug:
Editing a csh file with no file extension gives the following error:

Error detected while processing BufReadPost Autocommands for "*"..function polyglot#shebang#Detect[7]..polyglot#shebang#VimDetect:
line    48:
E117: Unknown function: dist#ft#SetFileTypeShell

To Reproduce:

1: PlugInstall vim-polyglot with default settings.
2: Create a script like:

#!/bin/csh
echo Hello World

3: Save w/o file extension (ERROR: test, NO ERROR: test.csh, test.sh)
4: Open file in vim (I'm using neovim 0.10.3)

Possible Fix:

When I changed all references in vim-polyglot/autoload/polyglot/shebang.vim from dist#... to polyglot#... the error disappeared and ft was correctly set to csh.
