[BUGFIX][Cache] Wincache backend class constructor

The class constructor of wincache cache backend misses the first
parameter $context, so $options is treated as $context. Given
backend options are not used this way, for example defaultLifetime
has no effect.
The patch adds the missing constructor parameter to be in line
with the other cache backends.
