gettokenbalances and getaccount sometimes cannot return BTC token balance

#### What happened:
When call getaccount and gettokenbalances, sometimes it cannot return the BTC balances

```
./src/defi-cli -testnet getaccount 7Jw72Q9yGJ1UWCXdQcUwkwSX48mkvdV2sS
[
"867.45064013@DFI",
"10100.00000000@ETH",
"10100.00000000@USDT",
"1.76692021@MOCK",
"10.21070861@MOCK-DFI"
]
```
The btc token ID is 1.
```
./src/defi-cli -testnet gettokenbalances
[
"867.45064013@0",
"10100.00000000@2",
"10100.00000000@5",
"1.76692021@8",
"10.21070861@9"
]
```

But after do a poolswap between DFI and BTC, then the BTC balances can show up.

```
./src/defi-cli -testnet poolswap "{\"from\":\"7Jw72Q9yGJ1UWCXdQcUwkwSX48mkvdV2sS\",\"tokenFrom\":\"DFI\",\"amountFrom\":\"1\",\"to\":\"7Jw72Q9yGJ1UWCXdQcUwkwSX48mkvdV2sS\",\"tokenTo\":\"BTC\",\"maxPrice\":\"100000.0\"}"

```
```
./src/defi-cli -testnet getaccount 7Jw72Q9yGJ1UWCXdQcUwkwSX48mkvdV2sS
[
"866.45064013@DFI",
"0.55820666@BTC",
"10100.00000000@ETH",
"10100.00000000@USDT",
"1.76692021@MOCK",
"10.21070861@MOCK-DFI"
]
```

```
./src/defi-cli -testnet gettokenbalances
[
"866.45064013@0",
"0.55820666@1",
"10100.00000000@2",
"10100.00000000@5",
"1.76692021@8",
"10.21070861@9"
]
```

#### What you expected to happen:

It should always show BTC token balances.

#### How to reproduce it (as minimally and precisely as possible):

It seems only happens to ICX maker bot node.
