Subject: [PATCH] Fix total count in flow tracker (#7813)

When you put the output of a bash command in a variable, it replaces the `\n` with a space. Using `ls` instead of `echo` fixes it

Test Plan:
Run

```
ALL_FILES=`find src -name '*.js' | grep -v umd/ | grep -v __tests__ | grep -v __mocks__`
COUNT_ALL_FILES=`ls $ALL_FILES | wc -l`
echo $COUNT_ALL_FILES
```

Make sure that it outputs 221
