title: SQLStorage Count(*) weird behaviour
body: <p>I'm using Ionic2 beta.4 SQLStorage, trying to count the occurrence of a value appearing in the column.</p>
  
  <pre><code>this.storage.query('SELECT COUNT(1) FROM dbstorage WHERE value = ?',[variable])
  </code></pre>
  
  <p>neither </p>
  
  <pre><code>this.storage.query('SELECT COUNT(*) FROM dbstorage WHERE value = ?',[variable])
  </code></pre>
  
  <p>works</p>
  
  <p>the following codes works fine for samsung android phone(lolipop), while it doesn't run for iOS or another android phone(kitkat). </p>
  
  <p>Insert , Select, Create Table statements work fine for all phones tested.</p>
  
  <p>Is there any workaround for this? Or do I have to use another simpler query statement?</p>
