"propertiesAreEqualToIgnoring" does not work for some property names

[tmohme]

The function is very useful but unfortunately Java introspection seems to have its own ideas about naming, so that properties are not ignored when their name starts with a lowercase letter immediately followed by an uppercase letter:

class PropertiesDemo {
    data class Bean(
        val lowercase: String,
        val camelCase: String,
        val bRoken: String,
    )
    val bean = Bean("bean", "bean", "bean")

    @Test
    fun camelCase() {
        val copied = bean.copy(camelCase = "different")
        expectThat(copied).propertiesAreEqualToIgnoring(bean, Bean::camelCase)
    }

    @Test
    fun lowerCase() {
        val copied = bean.copy(lowercase = "different")
        expectThat(copied).propertiesAreEqualToIgnoring(bean, Bean::lowercase)
    }

    @Test
    fun bRoken() {
        val copied = bean.copy(bRoken = "different")
        expectThat(copied).propertiesAreEqualToIgnoring(bean, Bean::bRoken)
    }
}

When you run the above tests, you'll find that strikt sees the property Bean::bRoken as "BRoken" and therefore does not ignore it and fails the test.
