[TextInputLayout] Fixed wrong position of the counter when helper or error text are removed

[gabrielemariotti]

It closes #1719

When the helperText or the errorText are removed and the counter is visible, the counter view has a wrong position.

It can be replicated in many ways:

        <com.google.android.material.textfield.TextInputLayout
            android:id="@+id/til"
            app:counterEnabled="true"
            app:counterMaxLength="6"
           ...>

with:

    val textInputLayout: TextInputLayout = findViewById(R.id.til)
    textInputLayout.setEndIconOnClickListener{
        textInputLayout.isHelperTextEnabled = false
    }
    textInputLayout.isHelperTextEnabled = true

or

    val textInputLayout: TextInputLayout = findViewById(R.id.til)
    textInputLayout.isErrorEnabled = true
    textInputLayout.isErrorEnabled= false
