Fix PHP 7.4 bug #159

[mstralka]

Sorry for the reformatting this was really only a few changes to fix #159 by changing several instances of:

if ($this->tenantTokens[$tenantKey] == null) {

to

if (!isset($this->tenantTokens[$tenantKey]) || $this->tenantTokens[$tenantKey] == null) {

and initializing $this->tenantTokens in the constructor instead of a local variable.

Can this be rebased on the latest instead of the 1.2.2 version?

Also, this change could be added, since it's for the same reason. It's confirmed by the existing CacheServiceTest::testWhenNewInstanceIsCreatedGetReturnsNull().

[iisisrael]

Actually this change as well.
