Reset laststatus for lualine

The bullshittery of workarounds we need just for lualine continues...

Of course lualine has hardcoded setting laststatus to some value with
their fucking useless globalstatus option [0].

Let's reset it after VimEnter again, just because lualine is a special
snowflake.

Top investigators around the world are still trying to find out why
anyone with a sane mind would use lualine's globalstatus option (that
sets laststatus=3 for them) instead of just directly setting
laststatus=3.

Fixes #53
