title: Room doesn't recognize some class parameters when creating select queries
body: <p>If I have a class/entity:</p>
  <pre><code>@Entity
  class Person(yearOfBirth: Int) {
    val ageInYears: Int
      get() = currentYear - yearOfBirth
  }
  </code></pre>
  <p>And want to create a Dao:</p>
  <pre><code>@Dao
  interface PersonDao {
    @Query(&quot;SELECT * FROM person WHERE ageInYears &gt;= 21&quot;)
    fun getAdults(): List&lt;Person&gt;
  }
  </code></pre>
  <p>I get an problem in the IDE that says &quot;Cannot resolve symbol 'ageInYears'&quot;.  It seems Room can't deal with parameters with getters.  Is there a way around this?</p>
