--test param throws error when args are added (--test="test --concurrency=1")

[m-skolnick]

The --test param seems to throw errors if args are added.

I am attempting to set the concurrency of my dart test command to a concurrency of 1.

command:

dart run coverage:test_with_coverage --test="test --concurrency=1"

output:

> dart run coverage:test_with_coverage --test="test --concurrency=1"

Could not find package `test --concurrency=1` or file `test --concurrency=1`

It seems to not like the extra parameters on the test command.

For example, this works as expected:

dart run coverage:test_with_coverage --test="test"

Any help would be appreciated!
