Remove redundancy in resolve error between main message and primary label
``` error[E0576]: cannot find method or associated constant `BAR` --> $DIR/issue-87638.rs:20:27 | LL | let _ = <S as Trait>::BAR; | ^^^ not found in trait `Trait` ``` instead of ``` error[E0576]: cannot find method or associated constant `BAR` in trait `Trait` --> $DIR/issue-87638.rs:20:27 | LL | let _ = <S as Trait>::BAR; | ^^^ not found in `Trait` ``` The general rule is that the primary span label should work well on its own (suitable to be shown in editors), while the main message provides additional context of the general case. When using `--error-format=short`, we concatenate the main message and the primary labels, so they should be complementary.
