Stop working with tpope/vim-unimpaired

[anuvyklack]

After 222a8ee a bug appeared.

To reproduce:

1. Install tpopt/vim-unimpaired
2. Press [<Space> or ]<Space> in any buffer to add empty line above / below the current line.
3. Press " to use registers.

After this I get message:

E5108: Error executing lua Vim:E121: Undefined variable: a:count

This bug existed before 222a8ee also.

This is my `:checkhealth` output, if it may help

This is a really weird bug. I have no idea where that a:count is coming from. Somehow the unimpaired code runs when pulling registers. Will investigate further.

[folke]

The problem was with the last expression = register, which is set by unimpaired and gave an error when executing. I simply wrapped pulling registers in a pcall to make it work again. Should be fixed now.

Everything works now! Thank you! Awesome plugin!
