Deprecation message of function 'the_msls' points to new function name 'msls_the_msls()' which does not exist #545

Describe the bug
Deprecation message of function the_msls() points to new function name msls_the_msls(). However this function does not exist. Should be msls_the_switcher().

The documentation also still has the old function in several places:
<?php if ( function_exists( 'the_msls' ) ) the_msls(); ?>

To Reproduce
Use <?php if ( function_exists( 'the_msls' ) ) the_msls(); ?> in a theme.

Expected behaviour
Depreciation message should point to msls_the_switcher()

Documentation should be <?php if ( function_exists( 'msls_the_switcher' ) ) msls_the_switcher(); ?>
