conflict between mounts in getKeys

[farnabaz]

Assume

/tmp <------- mount point /tmp/s1-1 /tmp/s1-2/ /tmp/s1-2/s1-2-1 /tmp/s1-3

/tmp/s1-2 <------- mount point /tmp/s1-2/s2-1 /tmp/s1-2/s2-2 /tmp/s1-2/s2-3

When we call storage.getKeys('/tmp/s1-2') we get:

/tmp/s1-2/s1-2-1 <---- This is odd behavior.
/tmp/s1-2/s2-1
/tmp/s1-2/s2-2
/tmp/s1-2/s2-3

having /tmp/s1-2/s1-2-1 in result keys is odd, and leads to invalid behavior. Since calling storage.getItem('tmp:s1-2:s1-2-1') result null

const storage = createStorage()
const storage1 = createStorage()
storage1.setItem('s1-1', 'bar')
storage1.setItem('s1-2/s1-2-1', 'bar')
storage1.setItem('s1-3', 'bar')
const storage2 = createStorage()
storage2.setItem('s2-1', 'bar')
storage2.setItem('s2-2', 'bar')
storage2.setItem('s2-3', 'bar')
storage.mount('/tmp', storage1)
storage.mount('/tmp/s1-2', storage2)

const keys = await storage.getKeys('/tmp/s1-2')

const content = await storage.getItem('tmp:s1-2:s1-2-1') # null
