mdTabs: md-input-container leaks watchers

[jmcpeak]

Watch count increases every time you change a tab with a md-input-container - tabs 1 and 2

This behaviour is not seen if you use a md-button - tabs 3 and 4

    <md-tabs>
      <md-tab label="1">
        <md-content>
          <md-input-container>
            <label>1</label>
            <input>
          </md-input-container>
        </md-content>
      </md-tab>
      <md-tab label="2">
        <md-content>
          <md-input-container>
            <label>2</label>
            <input>
          </md-input-container>
        </md-content>
      </md-tab>
    </md-tabs>
  </md-content>

Hmmm, tab change seems to new a controller every time...

+1, this results in huge leaks in only moderately complex forms, when the workflow consists of switching semi-often between tabs.
