Completing parens on functions with some Lsp (like phpactor) render an error

[gbprod]

Description

When completing a function's parens, it renders an error because item.data is not an array:

Error executing vim.schedule lua callback: ...vim-autopairs/lua/nvim-autopairs/completion/handlers.lua:15: attempt to index field 'data' (a number value)

        vim/_editor.lua: in function <vim/_editor.lua:0>      

It happens using phpactor. It could be fixed with #270.

Steps to reproduce

Setup phpactor Lsp and complete a function.
