Wrong automatic indentation after trailing operators

[michalmuskala]

Describe the bug
Given the code below:

function() ->
    expr() andalso
        expr().

pressing enter indents the cursor by 8 spaces to align with the final expr().. We end up with:

function() ->
    expr() andalso
        expr().

        |

This is also visible when pasting some code after similar function. For example, manually removing the extra indentation, and then pasting function2() -> ok. ends up with:

function() ->
    expr() andalso
        expr().

    function2() -> ok.

In this case the final indentation is only 4 spaces, rather than the 8 spaces produced by simply pressing enter.

Expected behavior
The indentation should be reset to the left margin given we're outside any function.

Context

• erlang_ls version (tag/sha): v0.0.32 of the VS Code extension

As a follow up. There's wrong un-indentation after case as well:

case test of
    test ->
        test|

with return:

case test of
    test ->
        test
        |

after typing end, it gets de-dented, but only by one level, leaving the indentation still incorrect:

case test of
    test ->
        test
    end|
