Fix databases truncated view bug

Summary:
The structure of the page is:
```
<FlexColumn>
  <Toolbar />
  <Content />
  <Toolbar />
</FelxColumn>
```

When Content is a FlexColumn, it doesn't play well with the others and uses all the space, to you don't see the bottom toolbar.
Changing it to a FlexRow fixes this. Also added an inner FlexColumn to make sure the behaviour for things inside Content isn't changed (flex-direction needs to be column in there).
