Flags for cargo run commands are passed to cargo build

Environment

• IntelliJ Rust plugin version: 0.3.138.3572-203
• Rust toolchain version: stable and nightly
• IDE name and version: IntelliJ Idea 2020.3.1
• Operating system: macOS Big Sur 11.1

Problem description

Flags for cargo run commands seem to be wrongly passed on to cargo build. When I add a new run configuration containing -l, I receive the following error message:

error: Found argument '-l' which wasn't expected, or isn't valid in this context

and

/Users/felixwiegand/.cargo/bin/cargo +stable build --color=always -l --message-format=json-diagnostic-rendered-ansi
error: Found argument '-l' which wasn't expected, or isn't valid in this context
USAGE:
    cargo build --color <WHEN>
For more information try --help
Process finished with exit code 1

Removing the -l flag makes everything compile and work as usual.

Steps to reproduce

Simply add a new run configuration with a flag that is not valid for the cargo build command.

There seem to be multiple issues all related to inappropriate command line arguments being passed to cargo. It would be extremely helpful to allow users to see, and override any options so that each one did not have to be it's own bug.
