TestStore_NoViableHead_Liveness Test Setup is Broken

[nisdas]

Describe the bug

TestStore_NoViableHead_Liveness no longer passes on develop and fails:

=== RUN   TestStore_NoViableHead_Liveness
    assertions.go:37: process_block_test.go:1709 Values are not equal, want: [213 22 225 129 1 18 226 25 79 68 143 221 214 65 77 248 255 141 14 123 148 221 139 14 239 228 161 66 200 230 161 231] ([32]uint8), got: [181 252 111 34 208 147 200 24 18 11 249 188 101 219 23 102 171 125 115 227 61 242 232 100 193 161 222 136 86 86 140 91] ([32]uint8)

Has this worked before in a previous version?

This has worked before this PR:
