[FIX] account: analytic account fix in multicompanies env

When using _prepare_analytic_distribution_line, it would take
the company for the line from the distribution, then the env.
This would cause multicompany issues in some case, creating the
line for the wrong company. By using current the move line to
get the company before falling back on the env, we can avoid such
an issue.
