Library used (support-v4, appcompat-v7, ...): recyclerview-selection
Version used: 28.0.0-alpha1
Theme used: Theme.AppCompat.Light.DarkActionBar
Devices/Android versions reproduced on: Emulator/ API26

This bug can be produced by this way:
1- Start selection
2- Select som items
3- DeSelect all items
4- Try to start selection from new
5- Exception ...

Hi, I just started using the recyclerview-selection new library for demo purposes, I discovered that when the multiple selection is used (withSelectionPredicate(SelectionPredicates.<String>createSelectAnything()) it works fine for the first time when all items are deselected but if we start selecting items from new (after deselecting all items) it generates an exception of type java.lang.IllegalStateException in the GestureSelectionHelper class at line 76.

This exception is due to failing in checking the state of mStarted in:
void start() {
checkState(!mStarted);
...
}

Which must be false. But, its value is true (because there was a first selection):

void start() {
checkState(!mStarted);
....
mStarted = true;
...
}

- Relevant code to trigger the issue.

mSelectionTracker = new SelectionTracker.Builder<>(
"string-items-selection",
mRecyclerView,
new StringItemKeyProvider(1, ITEMS),
new StringItemDetailsLookup(mRecyclerView),
StorageStrategy.createStringStorage()
).withSelectionPredicate(SelectionPredicates.<String>createSelectAnything())
.build();

- A screenrecord or screenshots showing the issue (if UI related).
