Twos: fix warning about extra paranthesis

Browse Source 
We have a comparison like `if (( a == b ))`, which is a parenthesis too
much, which generates the following warning

```
InfiniTime/src/displayapp/screens/Twos.cpp:133:35: warning: equality comparison with extraneous parentheses [-Wparentheses-equality]
  if ((grid[newRow][newCol].value == grid[oldRow][oldCol].value)) {
       ~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~
InfiniTime/src/displayapp/screens/Twos.cpp:133:35: note: remove extraneous parentheses around the comparison to silence this warning
  if ((grid[newRow][newCol].value == grid[oldRow][oldCol].value)) {
      ~                           ^                            ~
```
