unable to build rls on nightly

[semarie]

while building rls (as embedded in rust tarball from nightly 8a87b94 2020-01-14), I have the following error:

   Compiling rls-rustc v0.6.0 (/data/semarie/build-rust/build_dir/rustc-nightly-src/src/tools/rls/rls-rustc)
error[E0609]: no field `continue_parse_after_error` on type `rustc::rustc_session::config::DebuggingOptions`
  --> src/tools/rls/rls-rustc/src/lib.rs:93:36
   |
93 |         config.opts.debugging_opts.continue_parse_after_error = true;
   |                                    ^^^^^^^^^^^^^^^^^^^^^^^^^^ unknown field
   |
   = note: available fields are: `codegen_backend`, `verbose`, `span_free_formats`, `identify_regions`, `borrowck` ... and 103 others

error: aborting due to previous error

It seems it is a fallout from #68024 which removed continue_parse_after_error field.

It should be fixed in today's nightly.
