Envars ignored in mutuallyExclusiveOptions

[amkad]

It looks like envvars in mutuallyExclusiveOptions do not work in 3.5.0

class SomeTool: NoOpCliktCommand() {
    val password by mutuallyExclusiveOptions(
        option("--password-file", envvar = "PASSWORD_FILE").file().convert { it.readText() },
        option("--password", envvar = "PASSWORD"),
    )
}

class Issue {
    @Test
    fun mutuallyExclusiveOptionsWithEnvVars() {
        val envvars = mapOf("PASSWORD" to "secret")
        val tool = SomeTool().context {
            envvarReader = { envvars[it] }
        }
        tool.parse(emptyList())
        assertEquals("secret", tool.password)
    }
}

org.opentest4j.AssertionFailedError: 
Expected :secret
Actual   :null

It works fine with 3.4.2
