Possible performance issue when Aztec is first launched

[rachelmcr]

The UI tests added in #382 use the Espresso framework, which can sometimes (depending on system load) turn a single click action into a long tap. (See Espresso code for details.)

While writing the tests, I observed that when I tried to click on a toolbar button first (before taking any other action in Aztec) it consistently became a long tap. However, if I enter text first and then click on a toolbar button, it behaves as expected.

This may indicate a performance issue when Aztec is first launched, causing the slower click action that triggers the long tap issue in Espresso.
