mapValuesDeep mutates the original object if leavesOnly: false

Hi,

Great library 👍

I found using mapValuesDeep that if the options are left at the default leavesOnly: false, then it mutates the original object. If leavesOnly: true then the original object is not mutated.

You can see an example repl.it here.

// leavesOnly: true
{ sourceData: { hello: 'world' }, mappedData: { hello: 'WORLD' } }
// leavesOnly: false
{ sourceData: { hello: 'WORLD' }, mappedData: { hello: 'WORLD' } }

Is this the expected behaviour?
