false-positive Unused Import when importing static java function

[Koriit]

Expected Behavior

Applying linter rule should not break the compilation.

Observed Behavior

There is a false-positive unused import. With hard linter check, cannot build because of linter error. If the import is removed cannot build due to compilation error.

There was no such issue in 0.37.2

Might be related to #845

Steps to Reproduce

This is tricky as I couldn't reproduce a "clean" scenario. However, this is a sample project that reproduces the issue with a google library that we had in one of my projects and which is affected: https://github.com/Koriit/issues-ktlint-872

Your Environment

• Version of ktlint used: 0.38.1
• Name and version (or code for custom task) of integration used (Gradle plugin, Maven plugin, command line, custom Gradle task): org.jlleitschuh.gradle.ktlint 9.3.0
• Version of Gradle used (if applicable): Gradle 6.5.1
• Operating System and version: Mac OS X 10.14.6 x86_64
• Link to your project (if it's a public repository): https://github.com/Koriit/issues-ktlint-872

@Koriit thanks for the report at the sample project. If you need to unblock yourself, the ktlint-disable directives should work; see the README for details.

Thanks for the suggestion!

I also reprodused the bug when there are static class import and concrete static class method import both:

import org.assertj.core.api.Assertions
import org.assertj.core.api.Assertions.assertThat

After removing static class import and leaving static method import all works fine.
