Incorrest hash counting of HashTable

[awen-li]

Description

During using the lib HashTable, the counting is unexpected when the item number is larger than the table size.

Steps/Code/Corpus to Reproduce

from bounter import HashTable

Ht = HashTable(buckets=4)

Loop = 8
ItemNum=8
print ("Loop = ", Loop)

for i in range (0, Loop):
    for s in range (0, ItemNum):
        Ht.increment(str (s))

for s in range (0, 8):
    print ("Ht[%d] = %d" %(s, Ht[str (s)]))

Expected Results

Ht[0] = 8
Ht[1] = 8
Ht[2] = 8
Ht[3] = 8
Ht[4] = 0
Ht[5] = 0
Ht[6] = 0
Ht[7] = 0

Actual Results

Ht[0] = 0
Ht[1] = 0
Ht[2] = 0
Ht[3] = 0
Ht[4] = 0
Ht[5] = 0
Ht[6] = 0
Ht[7] = 1
